please answer me my questions ​

Answer 1

Solution :-

➻ Area of Polygon (ABCDEFG) = Area of Trapezium(AEFG) + Area of Trapezium(ABCH) + Area of Trapezium(HCDE)

we know that,

• Area of Trapezium = (1/2) * (sum of parallel sides) * Height .

So,

➻ Area of Polygon (ABCDEFG) = [(1/2) * (10 + 7 + 7.5) * 4] + [(1/2) * (4 + 4 + 2) * 10] + [(1/2) * (4 + 2 + 5) * 7]

➻ Area of Polygon (ABCDEFG) = [2 * 24.5] + [5 * 10] + [3.5 * 11]

➻ Area of Polygon (ABCDEFG) = 49 + 50 + 38.5

➻ Area of Polygon (ABCDEFG) = 137.5 cm². (Ans.)
